The check engine light CEL on the Tucson often illuminates due to a range of engine-related problems. Common causes include faulty oxygen sensors, malfunctioning mass airflow sensors, loose o r damaged gas caps, o r issues with the catalytic converter. In Pakistan, poor fuel quality can trigger sensors to detect inefficient combustion o r emissions, causing the CEL to turn on. Dirt, dust, and moisture also contribute to sensor malfunctions. Owners should use an OBD-II scanner to diagnose specific fault codes and address the underlying issue promptly. Routine maintenance and quality fuel help reduce CEL occurrences.
